A former math teacher at a Long Island school has been charged with larceny for accepting paychecks that mistakenly continued to be sent to her bank account.

Sharnett Morgan, 24, of Queens, faces up to seven years behind bars if convicted of not returning more than $28,000 in payroll checks sent from Hempstead HS, said Nassau County District Attorney Denis Dillon.

“By taking money that she did not earn, Morgan was not just stealing from school-district authorities, but from taxpayers and families,” Dillon said.

He said Morgan worked as a substitute at the school from September 1999 to June 2000. But, due to an administrative error, checks continued to be sent the following school year, directly into Morgan’s bank account.

The bookkeeping error was discovered earlier this year by the school district, which attempted to recover the money.

But Morgan – who allegedly had already spent most of the money for personal bills – denied she had received any of the checks, said Dillon.
